usually of mawkish flavor and odor resembling that of chlorin; lamellae usually adnexed<br />
and rather narrow, occasionally free and rounded behind, more or less crowded, white; spores<br />
ellipsoid, smooth, hyaline, very variable in size, 7-14X5-9 ¿i; stipe subequal, usually radicate,<br />
bulbous or enlarged or equal below, concolorous or paler, mealy above, squamulose or imbri-<br />
cate-squamose below, solid or slightly spongy, 4-15 cm. long, 1-4 cm. thick; annulus white,<br />
apical, fragile or lacerate, often appendiculate or evanescent; volva white, usually friable,<br />
rarely remaining as concentric, margined scales or a short limb at the base of the stipe.<br />

DOUBTFUL SPECIES<br />
Amanita abrupta Peck, Bull. Torrey Club 24: 138. 1897. Known only from specimens<br />
collected by Underwood and Baker in woods near Auburn, Alabama. It is near Venenarius<br />
solitarius, but the slender stipe terminated below by a large subglobose bulb distinguishes it'<br />
from the forms of that species with which I am familiar. It is very desirable that fresh speci-<br />
mens be obtained and color sketches or photographs be made from them for comparison with<br />
V. solitarius and V. cothurnatus.<br />
Agaricus bulbosus vernus Bull. Herb. Fr. pi. <strong>10</strong>8. 1782. It is doubtful whether this is<br />
really distinct from Venenarius phalloides, although some European mycologists maintain that<br />
the spores are different. I have been unable to find any <strong>North</strong> <strong>American</strong> specimens that<br />
could not be referred to the white form of V. phalloides.<br />
Lepiota drymonia Morgan, Jour. Myc. 13: 13. 1907. Collected in Vermont, on the<br />
ground in woods. Probably a form of Venenarius solitarius.
